2024 PN NCLEX Questions Nursing Practice Question
The client has an order for an IV piggyback of Ceftriaxone 750mg in 50mL D5W to run over 30 minutes. What is the appropriate drip rate?
Correct Answer: A
Rationale: To determine the appropriate drip rate for the IV piggyback of Ceftriaxone, the total volume of 50 mL needs to be infused over 30 minutes.
Calculating the drip rate involves converting the time to hours: 30 minutes is 0.5 hours. The formula for drip rate is total volume (mL) divided by time (hr). Thus, 50 mL ÷ 0.5 hr = 100 mL/hr.
Option B (150 mL/hr) would over-infuse the solution in 20 minutes, while Option C (200 mL/hr) would complete it in just 15 minutes, both risking potential complications. Option D (50 mL/hr) would take 1 hour, delaying treatment. Therefore, 100 mL/hr is the only rate that aligns with the prescribed infusion time.
